The inner end is provided with a cavity 21, in which is inserted a hardened steel disk 22; Upon this steel disk is the apertured phosphor bronze bearing 23, which is accurately drilled. to receive the pivot 19.,- on the end oi the governor shaft. Both pivot bearings 11 and 12, have their extreme ends hardened and ground spherical; The bearing 18, thus bearing 26, which consists of a rectangular block of metal with a screw threaded aperture 27, to receivea screw 28, which passes through the slot 25, and by which the block 26, is firmly held in any adjusted position within the groove 24. In the end of the block 26, there is'an aperture 29, in which is fitted a small steel disk 30, which serves as an end thrust for the pivot 11. The

, sleeve bearing 31, is a duplicate of the bearang 23, at the opposite end of the governor shaft, being made of phosphor bronze. The block 26, provided with a' small ball handle 32, by which it may be pushed or pulled along the groove 24, when the set screw 28, is slightly slacked oil.

The adjustment of the motor is accomplished by the operator in the following manner:

The i-notor is set running with the worm 9, in engagement With the worm wheel 8. The operator then slightly slacks up the set screw 28, and then with his ear close to the running motor adjusts the block 26, back and forth in the slot 2i, until the adj ustment is such that the worm gear is absolutely silent. The operator depends entirely upon his acute sense of hearing to accomplish accurate adjustment. When the point reached at which no sound is given out by the worm gear, the operator then turns the set screw 28, up tight. He then adjusts the bearing 18, by slacking set screw 20, and pushing in or pulling out said bearing until there is only a very minute end play for the shaft. He then resets the screw 20, and the adjustment is complete.

It will thus be seen that the adjustment of the worm 9, is towarii and away "from the worm wheel 8., in a straight line, and with the worm and wheel accu 'ately cut as they usually are, there will beno binding of parts either in the bearings, or between worm and wheel. When no audible sound comes from those parts the operator may know that his adj ustmcnt is correct By my improvement 1 am able to make a great saving in cost of construction over previous forms of governor shaft adjustments, and what is more advantageous a very; great saving in time occupied in sembling and adjusting. The plUCllHSlTlg public more critical now than formerly, and the manutacturer is required to give much attention to accuracy of detail, and the present in'iprovement is but another step in that direction.
